A tensioning bar assembly for a tensioning assembly of a drive system of an agricultural machine includes a longitudinal bar having a top end, a bottom end, and a threaded portion. An attachment device is coupled to the top end to attach to a tensioning arm. A compression spring is located around a portion of the longitudinal bar. A first spring retainer engages with and retains a first end of the spring. A first locking nut fits to the threaded portion of the bar and retains the first spring retainer longitudinally in place relative to the bar. The longitudinal bar is rotationally freely coupled to the attachment device to permit free axial rotation of the bar about its longitudinal axis relative to the attachment device, and an engagement head is attached to and located at or proximate the bottom end of the longitudinal bar for engagement with a tool.

The skid steer manure spreader attachment includes a main bucket compartment, a cover, and a beater shaft. The bucket, cover, and beater shaft are preferably formed of welded steel. The bucket has an industry standard quick attach plate on the back so it can be quickly attached to any standard skid steer, and is a standard width. A hydraulic motor operates the beater shaft and the cover. The beater shaft has blades angled in two directions. The beater shaft spins forward so the beater blades through manure out of the top of the bucket, above the shaft. The hydraulic motor drives the top sprocket, and a chain drives the bottom sprocket. A tensioner pivots on one screw to allow the user to tension the chain as needed.

A rotation mixer including a housing, a drive unit coupled to the housing, a carriage mounted on the drive unit for rotation relative to the housing, and a basket mounted for rotation relative to the carriage. The basket receives material to be mixed. The carriage includes an arm and a drive line coupled to the arm. The arm is mounted on the drive unit for rotation about a first axis relative to the housing, and the drive line converts rotation of the arm into rotation of the basket about a second axis relative to the arm during use of the rotation mixer. The drive line illustratively includes a belt and plurality of pulleys upon which the belt travels in a continuous loop, the belt engaging with a gear on the basket to cause rotation of the basket.

A spring compressor tool is provided. A tool for compressing an inline spring-loaded serpentine belt tensioner used in motive power systems, comprising a frame affixed with a fastening pin, the fastening pin optionally inserted into a hollow axle of the inline spring-loaded serpentine belt tensioner. A threaded stud affixed to an end of the frame, the threaded stud optionally coupled to a yoke providing lateral movement of the yoke along the threaded stud. A threaded fastener optionally coupled to the threaded stud and the yoke restricting movement of the yoke, the yoke optionally coupled to an end of the inline spring-loaded serpentine belt tensioner opposite the fastening pin. A lip attached to the yoke, the lip grasping the end of the inline spring-loaded serpentine belt tensioner, movement of the yoke along the threaded stud controls extension and contraction of the inline spring-loaded serpentine belt tensioner.

In an embodiment, a tensioning apparatus includes a housing and a fastener extending at least partially through the housing. The apparatus also includes a trolley adjustably positioned within the housing about the fastener. The apparatus also includes a pulley disposed outside the housing and coupled to the trolley, where the pulley moves in unison with the trolley along an opening in the housing.

A sheave/sprocket tension adjustment and alignment tool (STAT) for adjusting alignment between a sheave/sprocket of a motor and a sheave/sprocket of an application machine includes a plate, a securing unit, and an adjusting unit. The plate has a first side and a second side, each of which is an opposite side of a plane of the plate. The securing unit is coupled to the first side of the plate and is configured to protrude in a first direction from the first side of the plate. The adjusting unit is coupled to a second side of the plate. The adjusting unit includes an adjustable protrusion that is configured to adjustably protrude in a second direction, which is substantially parallel to the plane of the plate.

Embodiments of the present disclosure include a drive belt tensioner configured to adjust tension in a drive belt of a blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system. The drive belt tensioner includes a mounting bracket configured to couple directly to a blower housing that is configured to house a blower of the blower assembly. The drive belt tensioner further includes an idler pulley configured to contact the drive belt. A position of the idler pulley is adjustable relative to the mounting bracket to enable adjustment of the tension in the drive belt.

A belt drive comprises a first pulley and at least one additional pulley and uses an elastic belt that is engagable over the pulleys. An auxiliary unit, connected to the first pulley, has a detent. A tensioning link comprises an open-ended slot for receiving in a slidable manner the detent. In an operating position of the belt drive the detent is locatable at a closed end of the open-ended slot and to obtain a belt changing position the detent is movable along the open-ended slot towards an open end of the open-ended slot. Movement of the detent along the open-ended slot requires simultaneous rotation of the auxiliary unit.

A chain tensioner device includes: a threaded bolt (3) for adjusting tension on a chain, that remains inserted in a part (4) integral with the wheel shaft (5), arranged in horizontal position, so that the tip (3a) of the bolt (3), presses on a second part (6) integral at the opposite end of the gear, so that tightening or loosening the bolt (3) determines a gap between both parts (4, 6) to regulate the tension and a discretization mechanism of the gap between the first part (4) and the second part (6) that includes at least a retractable element (8) either in the bolt (3) or in the first part (4) that contacts and is fitted in one of the series of slots (11) provided either in the bolt (3) or in the first part (4) so that it is possible to know the tightening or loosening of the bolt (3) applicable in each action.

In an embodiment, a tensioning apparatus includes a housing and a fastener extending at least partially through the housing. The apparatus also includes a trolley adjustably positioned within the housing about the fastener. The apparatus also includes a pulley disposed outside the housing and coupled to the trolley, where the pulley moves in unison with the trolley along an opening in the housing.
